Its biggest weakness: ChatGPT often misinterpreted information or issued outdated advice about health screenings recommended before beginning an exercise program.

The study also found the readability level of the recommendations was typically at the college level, which could be difficult to comprehend for many users and create “barriers to understand and apply the information provided.”
